Chipmaker ARM has introduced its energy-efficient Cortex A7 processor which extends smartphone battery life five times.

ARM claimed its latest Cortex A7 family of processors is its most energy-efficient application class processor. ARM said it will provide a richer user experience in entry-level smartphones.

Simon Segars, president at ARM, also introduced big.LITTLE processing.

Big.LITTLE processing combines two different processors in the same system on a chip (SoC). The lower-power Cortex A7 runs the operating system (OS) while greater demand tasks migrate to a higher-performance processor in 20 microseconds.

"One of today's technology's most significant challenges is how to create a SoC that meets the conflicting consumer demand for devices with both higher-performance and extended battery life," said Segars.

He added: "Big.LITTLE processing, enabled by Cortex-A7, achieves this by pairing the best of the high-performance Cortex-A15 MPCore and ultra-efficient Cortex-A7 processors."
